I found a neat illusion online, based on a folded paper dragon. I printed one off and folded it up…pretty freakin’cool!
I made a Blender version, I plan to make a realtime version…or even a VRML one if I can manage.
Here’s the blend file of it 261KB
Simply hold the center mouse button to rotate the view and the dragon appears to follow you!
The texure should be packed with the file, which includes folding instructions if you want to print one off and try it yourself. For best results, stand back about 2’ away and close one eye.
Stay tuned for the realtime version!
